【摘要】 本文采用高阶单步力控制试验方法,提出了减少试验误差的若干处理技术,进行了三层底部框支配筋砌块短肢砌体剪力墙足尺结构的拟动力试验,实现了大刚度多自由度复杂结构拟动力试验。试验结果表明,足尺拟动力试验可以很好地反映结构在真实地震作用下的反应,而采用力控制试验方法在结构恢复力特性进入下降段之前是可行的。更多还原

【Abstract】 The authors conducted the full-scale pseudo-dynamic test of the three-story frame-supported reinforced concrete short-limb masonry shell wall structure by using the high order single step force-control testing method,presented a processing technology for reducing the testing error and performed the pseudo-dynamic test of the large-stiffness and MDOF structure.The testing results show that the full-scale pseudo-dynamic testing can get the structure responses under the real seismic action and confirm that the force-control testing method is feasible before descending segment of structure restoring force.更多还原
